Try erasing the computers memory.

1) Disconnect both + and - battery cables
2) Clamp + and - battery cables together, don't let them touch the battery terminals.
3) Wait 10 minutes
4) Reconnect battery
5) Try starting it

If this doesn't work you can try to disable to security system.

No need to disconnect batteries. Just unclamp the ecu for 5 minutes then fix it back again. Codes deleted.

However, this would not disable the security system. The EWS2 delete thread might be helpful. Please search for it on these forums.
